Cardinal Keith O'Brien has admitted at times "my sexual conduct has fallen below the standards expected of me as a priest, archbishop and cardinal" in an issued statement.
The Cardinal resigned last Monday from his position as Britain's most senior Roman Catholic cleric.
His departure came a day after the Observer newspaper reported that three priests and a former priest had complained about him to the Vatican over alleged "inappropriate" behaviour stretching back 30 years.
Tonight's statement was issued by the Catholic Church in Scotland.
